TWO Grove-built Williams FW30s will take to the track carrying the handwritten best wishes of the team's seven World Champion drivers.

Revealing the fifth in a series of six anniversarial racing liveries today at the Circuit de Catalunya in Barcelona, Alan Jones, Keke Rosberg, Nelson Piquet, Nigel Mansell, Alain Prost, Damon Hill and Jacques Villeneuve all sent the team personal congratulations as it embarks on its fourth decade of Formula One and at the Italian Grand Prix later this year, will record its 500th Grand Prix start.

With comments as suitably Australian as "I was the first" from Alan Jones to Nigel Mansell's "Fabulous 28 wins, Red Five", the livery is a celebration of some of the most evocative and talented names to have graced the sport in the past 30 years.

The 1982 World Champion, Keke Rosberg, for his part said: "Thanks.for four great years" and Alain Prost, Williams' 1993 Champion added, "Many thanks to all the team - I was proud to win my last World Championship with you."

The team's most recent title winners, Damon Hill (1996) and Jacques Villeneuve (1997) said in turn "Thanks Frank" and "Thanks for three amazing years and the championship."

In addition to the good wishes from the seven World Champions, the 31 drivers who have raced for the team in almost as many years will grace the monocoque top, including names such as Ayrton Senna, Mario Andretti, Carlos Reutemann and Clay Regazzoni to current racers including Jenson Button, Juan Pablo Montoya and David Coulthard.
